ment over my Patent No. 1,911,702 granted May overlapping flap ends of the side and bottom pan- H els at the rear providing a sturdy, rigid and dillplytab formation in a close fit into akeeper-slot therewith, either, at the upper roof panel or at the bottom panel, or at both of the upper roof and bottom panels thereof, and further which, if a bird-house, may be secured to a tree, post, wall or the like, by driving a nail through the upper and lower tabs.

Another salient feature of the invention is the I adaptability with a slight modification of using the same principle of a cut blank for thefolding;

and interlocking means for box containers, in which the upper interlocking tabs are printed for the chimney, windows and doors printed on the outside panels, these ornamental features printed thereon "may be to suit any type or design of house desired; The printed housefeature may apply also to the bird-house, but it has been found that plain wood finish colors are best for the exterior panels of the bird-houses, so as to match in=with the trees secured to.

Other features of theinventionwill appear as the description proceeds in the following specification accompanied by the annexed drawings,

which is provided with a keeper-slot 3L The front panel I is further providedwith a suitable ingress opening 32 and a small hole 33 through which a perch stick 3.4 asshown in Figure 1, may

- be inserted-to a similarhole 33" in the side panel 5, so the end of the perch-stick may be near the opening 32 for use of the mother bird tofeed This description of the cut blank as shown in 1 Figure 7, may be appliedto Figures 1, 2, 3, 4, and

5, wherein the blank is assembled in a set up for The bottom panel H is provided pose, terminating in edges ll and ll thatyconfit and contact adjacent the creases 8 and 9,.of

The roof panel 26 has cut slits 25 and 26* corresponding to the oblique edges ii and M of the vertex portions 6 and l of the side panels 4 and 5, in order to provide the eave portions E on the side of the house.

' In Figures 8 and 9, a bird-house is shown em-;

bodying the same folding and set-up operations as the bird-house hereinbefore described, in which the same numerals in the description thereof will be primed for similar parts. In Figure 10 the cut blank shows the crease lines 2', 3, 8, and 9' in parallel relation to each other, thereby providing panels with right angle corner portions, thereby allowing square or oblong panels.

Figure 11 showsacandy box similar to the house form shown in Figures 8 and 9 and made from a blank similar to that shown in Figure 10, the tabs l3 and l3 and the openings 32, 33" and 33", and 6&3 being omitted, the tabs 92" and 12" being printed to resemble the. chimneyof a house, and the outer surfaces of the panels being printed to show a window W, a door D, and roofing 28. ,3

It will be understood that in the blank shown in Figure 10 the front, side, rear, top and bottom panels 5', a, 5', ill" and H, respectively, have 1 similar folding 01' creaselines 2', 3', 839, l6,

I8, 25 and 26', and interlocking tabs i2, i2" and 25!,and keeper-slot 3! as the blank shown in Figure 7, are all similar in construction and purpose although the size and shape of each may lower tabs Stand l3 and similar primed tabs of.

the modifications shown in Figures 8, 9, l and 11, for example, the securing of the tab portions has been shown for. nailing through the holes M, I4, l lfland M for securing to the support the fioor panels l! and ll" in Figures 7 and 10,

may or'may not be used to insert the tabs it and I3. therethrough, andthe tab 20 of the panel: l9 then assumes the rearward tab in place of the tab E2 of the panel H, as shown in Figure 6; If the slot 59 as shown tends to Weaken the bottom ll and H the slot 60 may be reduced in width and also the tabs l3, l3, l3", and '3" reduced in width accordingly. It is. a matter of preference in folding the end flaps Ill, ll and the rear panel it and end flaps I0, I l and rear panel l9 to suit whichever is preferable.

It is to be understood I do not wish to confine myself to any exactness ofany detail of shapeor design, material or construction, and reserve the right to make any alteration thereof that my come within the spirit of this invention andthe one of said panels being provided with a keeperslot, said panels including rear flap ends and a rear panel having tabs overlapping in a threefold formation and snugly secured into said keeper-slotof one of said gable roof panels thereby providing an assembled house structure without any corner bracing therewith.
